    F-16 Pilot- Chris Lehto analyses Gimbal footage

    It's already happening, estimating the bank angle from the artificial horizon is better than assuming 3 degrees. But it's all lost in the noise. We are already at the point where we have videos from guys like sim pilot Alpha Check about the complete infallibility of US military systems, and...

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    Any optical imperfections on a close non focussing element will generally only show up as glares for bright light sources. The window over the camera here acts a bit like a "UV filter" on a normal camera lens, and having a dirty/scratched UV filter can lead to glaring for strong light sources.

    Gimbal distance and Speed Range Estimates using Lines of Bearing and/or DCS

    No, we know from analysis of the artificial horizon marker on the footage the bank angle of the jet, knowing this bank angle gives us the turning circle. Of course they could have turned faster if they banked more sharply or used more control surfaces, but the HUD shows a steady bank angle...

    Gimbal distance and Speed Range Estimates using Lines of Bearing and/or DCS

    He was an F/16 pilot perhaps that jet does a tighter standard turn than the F/18. Different planes have physical limits of the turns they can do at certain banks based on altitude/speed etc. Don't confuse bank angle with turn angle.

    Comprehensive UAP Hypothesis

    This is where totally independent witnesses can be more accurate than witnesses who are collaborating, they start with an initial error and then make further wrong assumptions based on the communication of that initial flawed assumption. The issue compounds itself.

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    I found this very interesting forums discussion on https://forums.eagle.ru/topic/272552-atflir-laser-in-aa-mastermode/ "Laser is not used for ranging in AA. The range is either from FLIR passive ranging or the FLIR Autotrack target merely being correlated to a Radar target and thus fused into...

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    That's not quite what I am saying, you do both you SLAVE then use optical, but SLAVE remains boxed, unless you turn it off for some reason.

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    I watched some more footage of sim videos using SLAVE RADAR and optical tracking it seems that in normal use cases you SLAVE ATLFLIR to the L+S and then always turn on optical tracking as well, I think the SLAVE is mainly to get the ATLFIR pointing and moving in the right direction but the...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    They rotate not only at the same time, but with the same speed/acceleration and the same amount as the "object".

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    It isn't that ATFLIR can't focus, it's that all camera systems have a hyperfocal distance at which point all objects are in focus. For my 560mm lens setup, the hyperfocal distance is 2027 meters (2 kilometres) That means something at 2 kilometres and something at 20 kilometres would both be in...

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    I think a discord would be useful, the amount of sources/data is getting overwhelming and discussions are probably needed.

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    He's wrong about ATFLIR as far as I can tell His assumptions seem to be ATFLIR in A/G mode - it isn't based on the sim manuals, it's in A/A. L is laser indicator - It isn't it's LTD/R on ATFLIR I can see that the laser ranger might give an invalid ground range under certain circumstances...

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    Until they start talking publicly and add some detail of what exactly they mean it's really hard what to make of this. I mean if you go back to basics, when the videos were released the accompanying analysis we were provided with was what we analysed against the video. This figure was accurate...

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    By HUD does he mean the actual HUD or the ATLFIR MFD overlay? The HUD (heads up display) is the clear plane of glass that data is projected onto in front of the pilots eyeline. The ATLFIR overlay is on a TV monitor (MFD) in the cockpit. You can estimate distance knowing the FOV and the size...

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    Possibly, but yeah it depends on what it providing the track, given tracks can be shared, there's likely some algorithms being ran to determine a track format that works relative to whomever is viewing it.

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    It gets really nuanced here all we know is that in GIMBAL the ATLFIR is not slaved to a RADAR track. In GO FAST (same crew/plane/flight) the same is true (no SLAVE), however when Go Fast acquires optical track, a range appears presumably from RADAR but we don't 100% know, the same is not true...

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    We have no testimony from the Go Fast pilots as far as I know. RADAR measures distance by bouncing a beam of EM off the subject and then doing maths on the returning signal. https://en.wikipedia.org/wiki/Radar#Distance_measurement How does the HUD know the size of the object? I'm sure pilots...

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    No, the laser keeps coming up 1. I don't think the laser is used to provide range in A/A mode at all, every document I find says the laser is used to provide ground range in A/G mode only. 2. LTD/R is not flashing in Go Fast anyway. 3. There's no documentation I can find to show that the ATFLIR...
